Q: Bridgeport Mill - Replacement motor like this?
Ok, so it's a 2J varispeed head...
I'm thinking... out loud... screw the varispeed with the expensive belt
and the incredibly expensive replacement motor - the mill has no motor
or varispeed pulley for the motor.
Why not a standard motor of requisite HP mounted on a plate where the US
Motor motor would usually go OR a random US Motor mill motor of 1.5 to 2
HP, standard pulley (I can always make one on the lathe...) AND a VFD??
Best of all worlds? Or nightmare?
Comments?
VFDs - what freq range is *necessary*? to 200Hz, to 400Hz??
If the motor is a 3450 RPM going from 50Hz to 200Hz makes that sucker
run damn fast!! ;_) What am I missing here...? I think the mill has a
high/low lever that is in the lower part of the head... so I'd still
have two ranges... yes?
